(ci. 19e-462i- This invention relates toan attachment for typographical line' casting machines, for wipingv mouthpieces of the machines, and the invention has for its primary object the provision of an attachment which will obviate the necessity of the operator of the typographical line casting machine leaving the keyboard of thel machine in order to manually wipe off the mouthpiece of the machine. The inventor contemplating in this connection, an attachment for the purpose stated, so constructed that it may be mounted upon a typographical line casting machine and be manipulated by the operator of the machine without the necessity of his eXpending the time and labor incident to leaving his seat and manually performing this task.

In Figure 1, there is illustrated as muchv of the typographical line casting machine yas is necessary to an understanding of the invention and in this figure, the numeral 1 indicates the mouthpiece of the machine.

In all typographical line casting machines, the molds are carried by a disk which revolves to casting position when the line of matrices is delivered to the rst elevator. ported on the mold slide. The mold slide is advanced to the line of matrices and a plunger forces metal through the holes in the mouthpiece, forming a solid slug carrying in raised characters a duplicate of theline of matrices. This action causes small accumulations of metal to gather on the mouthpiece. My invention wipes off these accumulations of metal, thereby preventing backsquirts and allowing the machine to cast perfect slugs at all times.

vThe primary object is to wipe the mouthpiece 1 with a downward stroke, after Vthe casting operation has taken place, thereby clearing the entire mouthpiece of any accumulated metal.

This result is brought about by the action of roller 20 being operated from a movable lever known as the space band lever. This action takes place when the wiper is working automatically. When the wiper is to be operated by hand, roller 20 is removed and the wiper is operated by pushing down handle 17.

In describing my invention in detail, references are made to the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views and in which-k Figure 1 is a perspective view illustrating the attachment embodying the invention mounted upon a typographical line casting Ymachine in juxtaposition to the mouthpiece.V

Figure 2 is a plan view of the device.

This disk is sup-- j Figure 3 is an elevation taken from the front of the machine.

Figure '4 is a side elevation taken from the mag-y azine side of the machine.

Figure 1 is a fragmentary perspective View of the wiper and its operating mechanism and associated parts. The mouthpiece of the pot crucible which is part of the typographical line casting machine is designated as 1. The blade with a facing of felt which comprises the wiper is shown as 2. The roller: 20 is the medium through which the wiper is operated by movement of the spaceband lever, when the wiper is operated automatically.

When the operator of the machine recasts lines, the spaceband lever remains stationary. If, for this or any other reason, it is desirable to operate the wiper by hand; the roller 20 is removed and the wiper operated manually by movement of handle 17.

Figures 2, 3 and 4 show how the wiper is attached to the fixed bearing 12 of the typographical Y prises a bearing indicated by the numeral 30 which is so formed as to be easily mounted upon a xed part 12 of a typographical line casting machine. Mounted therein for rotary motion is a shaft 15 which projects beyond the ends of the bearing. The end of the shaft 15 is drilled with a 11g inch hole 36 for retaining aL spring which returns wiper to normal position after operation is completed. Clearance cut 18 is made in the shaft in order to give free passage to the long finger of the line delivery carriage when the machine is inv action.

The wiper blade 2 is fastened to bearing 4 by two 8x32 screws 5 and held in proper position by two dowel pins 6.

Sleeve 10 is a bearing through which passes shaft 7. This sleeve 10 is drilled and tapped to accommodate a set screw, which by pressure on shaft 7 holds the wiper Vin the proper position. When adjusted properly, the setting is retained by lock nut 9.

The shaft 15 rotates the wiper blade by the movement of the spaceband lever whichn turn is actuated by the line delivery and transfer cam; the lever and cam being parts of the typographical line casting machine proper. When the spaceband lever is actuated forward it forces roller 20 to roll in an upward direction along its surface thereby causing wiper 2 to wipe across the mouthpiece with a downward stroke. This movement is so timed as not to interfere with the action of the machine. The wiper is returned to normal position by action of spring 16.

The roller 20 has a combination of two connecting rods 21 and 23 which are fastened together by a screw and lock nut 25. This furnishes friction which prevents jamming the wiper 2 against the mouthpiece. The roller 20 is fastened to connecting rod 21 by a screw and lock nut 22. The connecting rod 23 is fastened to bracket 19 on the square cut raised boss` A felt facing is fastened to the wiper blade 2 by small brass rivets 35.

The stationary bracket 30 has a 31g inch hole 33; into which end of spring 16 is inserted.

Shaft 15 has a finished handle 17 joined to its forward end to facilitate operation by hand.

From the foregoing description, itis readily Seel) that this mouthpiece Wiper as designed and invented by me is a new and improved wiper. It Works automatically or manually atthe, will of the operator. It cleans the mouthpiece on both the downward and upward strokes. Cleaning the mouthpiece twice in one complete revolution of the machine produces a perfect lock up and solid slug at all times.

What is claimed is:

1. In a typographical line casting machine, a mouthpiece wiper blade adapted to swing in a vertical plane about a pivotal shaft, a curved arm on the inner end of the pivotal shaft connected at its other end to the Wiper blade, an extensible stud mounted on the top of the curved arm and at its other end connected by a. friction joint to an arm having an operating roller for engagement with a space band lever for operating the wiper downwardly and a spring for operating the wiper up- Wardly.

2, 1n a typographical line casting machine, a mouthpiece wiper blade adapted to swing in a vertical plane about a pivotal shaft, a curved arm on the inner end of the pivotal shaft connected at its other end to the Wiper blade, operated manually by the operator of the machine by a handle Situated in a CODVQnient position.
